"Your brother, the demigod. A super soldier, a living legend who kind of lives up to the legend. A man with breathtaking anger-management issues. A couple of master assassins. And you, big fella, you've managed to piss off every single one of us," Tony Stark says.

Audiences will finally be able to see which side prevails when the long-awaited "Avengers" finally hits theaters in a few weeks, on May 4. The fight has been years in the making, with the lead-up spread over five films thus far, from the first "Iron Man" to "Captain America: The First Avenger."

We know from the trailers and the clip that the fight between Loki and the Avengers will be a little more even when the time comes, but the identity of the alien "army" remains a mystery. Tom Hiddleston stopped by MTV News last year to talk about his work on "The Avengers," and he hinted that when the secret is revealed, it will definitely please fans.

"Loki has help, obviously, because if Thor could beat Loki on his own at the end of 'Thor,' surely why, logically, does it take eight of them to beat him this time?" Hiddleston revealed.

"Also, there is an evolution to Loki as well," he explained. "He's more self-possessed; he's more menacing. If the Loki in 'Thor' was about a spiritual confusion — 'Who am I? How do I belong in this world?' — the Loki in 'Avengers' is 'I know exactly who I am, and I'm going to make this world belong to me.' "
